PocoMail

PocoMail, PC Magazine Shareware Program of the Year 2000, was
developed from the ground-up to protect users from viruses and spam
that plague other
commonly used products. This means that PocoMail is powerful, fast,
secure, safe and easy to use and maintain. Features include:
intelligent junk-mail filters, message scripting, message templates,
mailing list support, POP and IMAP functions, HTML support, multiple
accounts, multiple address books, multiple signatures, optional skins
to change application appearance, nested mailboxes, fully
multi-threaded operation, display attachments inline without
launching external viewer, automatic backup of your mail and program
data, and many more. PocoMail will even check your spelling!

For administrators, moving PocoMail installation from one computer to
another is as simple as copying the install directory, as PocoMail
does not install any DLLs on the user's computer. Mailboxes are kept
in the standard mbox format, address books and filters are in the
standard CSV format.

With PocoScript, you can extend PocoMail's
functionality without having to program external DLLs or plug-ins.
You can create and edit PocoScripts directly from PocoMail.
PocoScript has access to all message parts so you can do advanced
processing of incoming mail, like stripping HTML content, or zipping
up attachments. PocoMail focuses on making email work for you.
